the absolute positioning is what keeps it from pushing everything else down. I had to lower the z-index as their example has a z-index of 3 or 5000 and so it was covering up all the content. the example also has an overflow:hidden on the body tag, but if you have any content this will cut it off, so i didn't add that either, but now it looks weird when you scroll down and the image ends since you can't set it to be 'fixed' like you could a background image.
